Being familiar with the conversion between milliamps and amperes can help you better maintain the electrical circuits in your home. Today, we will analyze the connection between amperes and milliamps, and how converting them can keep the circuit operating normally.

To understand the conversion rate between them, we first need to understand what electric current is. Electric current refers to the flow of electric charge. The more charge that passes through the cross-section of a conductor in a unit of time, the greater the intensity of the current. The unit of measurement for current intensity is the ampere. The ampere is a relatively large unit of measurement, with smaller units including milliampere, microampere, and nanoampere.

What Is An Ampere? 

Ampere is abbreviated as “A” and is one of the base units in the International System of Units (SI). We use it to measure the intensity of electric current. The higher the value of the ampere, the greater the intensity of the current. Conversely, the lower the number of amperes, the weaker the current intensity.

Amperes are typically used to describe larger currents, such as those used by large household appliances like refrigerators and washing machines, as well as industrial equipment. Additionally, the ampere unit is widely used in ammeters, power supplies, and electrical specifications.

What Is A Milliampere? 

A milliampere is a small unit of electric current represented by the symbol ‘mA’. It is used to denote smaller values of electric current. The milliampere is commonly found in the measurement and specification of electric current in electronic devices such as calculators and smartphones, biomedical equipment, as well as in precision instruments.

How To Convert Milliamps To Amps? (mA to A) 

Conversion Formula

1 ampere is equal to 1000 milliamperes

1 milliampere is equal to 0.001 ampere

1A = 1000mA, 1mA = 0.001A

 

From the above formulas, it is understood that to convert milliamperes to amperes, you take the value in milliamperes and divide by 1000.

[?]A = [?]mA / 1000

Assuming the value in milliamperes is 3000, then converting to amperes would be:

[?]A = [?]mA / 1000

= 3000mA / 1000

= 3A

How To Convert Amps To Milliamps? (A to mA)

To convert amperes to milliamperes, the same formula is used, which is to multiply the value in amperes by 1000.

[?]mA = [?]A * 1000

Assuming the value in amperes is 5, then converting to milliamperes would be:

[?]mA = [?]A * 1000

= 5A * 1000

= 5000mA

Online Converter

Apart from using a calculator to apply the formula to find the corresponding values in amperes or milliamperes, you can also use related online converters where you input the numeric value to get the answer directly. For example, by entering ‘convert mA to A’ or ‘convert A to mA’ into a web browser, you can find corresponding websites.

FAQ

Is 1 Amp The Same As 1000 Milliamps?

Yes, the conversion formula is mA = A * 1000 = 1A * 1000 = 1000mA, so 1 ampere is equal to 1000 milliamperes.

How Many Amps Is 50 mA?

By using the formula: A = mA / 1000 or an online converter, we can determine that 50mA / 1000 = 0.05A.

2.5 mA To Ampere

By using the formula:  A = mA / 1000 = 2.5mA / 1000=0.0025A
